8/8:There are lots of question marks surrounding Tiger Woods in the run-up to this week's PGA Championship. Woods played poorly last weekend at the WGC-Bridgestone Invitational. He appeared tired and fatigued over his final 36-holes. It is a legitimate concern that DFS fans must consider this week. The 42-year-old has played a ton of golf in the past six months. His age, injury history, and long stretches of inactivity in prior years are all factors in Tiger's current physical condition. He is a prime DFS contrarian target, as his ownership projection is very low and we have seen the 14-time major winner do incredible things in the past.--Joe Nicely - RotoBallerSource: PGA Tour
